PerfectPixel
Chrome extension overlaying mockups on live pages

About
Drop your mockup on the live page. Catch the misaligned padding, the mismatched color, the wrong font size.
Tune opacity, position pixel-by-pixel, and use blend modes to highlight every mismatch
Lock the overlay, click through to page elements, and tweak your CSS in real time
Overlay the design directly on your page for a pixel‑perfect match. Catch every mismatch before it ships, in development or visual QA, whether the code is hand‑written or AI‑generated.
